Filmmaking Dictionary: Number 1 / 1-Sheet (One-Sheet Film Poster)
Definition
A one-sheet is a principal promotional poster for a film. It presents the title and a clear visual identity, often with key cast names, a tagline, billing and release information. A common modern US theatrical size is 27 × 40 inches.
The term does not guarantee one universal size. Older posters and international markets use different dimensions. It can also be used more loosely for a single-page promotional or sales document, so clarify whether the request is for poster artwork or an information sheet.
What the Poster Needs to Communicate
A good one-sheet gives the audience a quick sense of the film’s genre, tone and central appeal. It does not need to explain the entire plot. The main image, title treatment and hierarchy should remain understandable at the viewing distance of the intended display.
- Title: Clear and legible within the overall design.
- Main image: A focused visual idea that fits the film.
- Key names or tagline: Used where they support the campaign.
- Billing and required marks: Prepared from the approved credit information.
- Release details: Appropriate to that version of the campaign.

Poster Versus Pitch One-Sheet
A pitch or sales one-sheet may include a logline, synopsis, team information and contact details. A theatrical poster has a different job: attracting attention and establishing the film’s identity. Trying to fit a full pitch document onto a poster often makes both functions harder to achieve.
For an independent short, the festival-facing artwork may need one set of information while a later screening announcement needs dates and venue details. Keep separate, clearly named versions so an outdated date or unapproved credit does not travel with the wrong file.
Preparing the Artwork
Obtain the actual printer or distributor specification before setting the canvas. Confirm finished dimensions, bleed, image resolution, colour requirements and accepted file format. Do not assume that an image sized for a social post will enlarge cleanly to a cinema display.
Review the spelling of every name and the approved billing order. Keep editable master artwork so the campaign can produce alternate sizes without rebuilding the design from a flattened image.
Common Mistakes
- Confusing a poster one-sheet with a one-page synopsis.
- Treating 27 × 40 inches as a worldwide requirement.
- Using low-resolution artwork stretched to print size.
- Sending a version with obsolete release information or unapproved credits.

Frequently Asked Questions
Must a one-sheet contain a plot summary?
No. A theatrical poster usually prioritises a concise visual message over a detailed synopsis.
Can one design serve print and online promotion?
It can supply the same visual identity, but each format usually needs a deliberate layout and export.
